Suppose the distance from the school to A is X kilometers, and the walking distance of the seventh grade team is Y kilometers. Let's establish the equation.

x + y = 2 1

x/60+2 1/60 = 10/60+y/4

Solution, x = 19, y = 2.

The first question: A collocation price is 2*2+4* 1.2=8.8 yuan. Similarly, B matches 25.6 yuan, and C matches 2 1.2 yuan.

Suppose B sells X and C sells Y, then A sells (58-3X-2Y)/2, and the equation is listed.

8.8 *(58-3X-2Y)/2+25.6 x+2 1.2Y = 44 1.2

Simplification: X+Y= 15

So the sales of fruit C is 150 yuan.
